Fortune reporter Jeremy Kahn spotlights a study co-authored by Prof. Marzyeh Ghassemi exploring issues associated with “explainable” AI systems that are being applied in fields such as healthcare, finance and government. The researchers explain that those using such systems “might have misunderstood the capabilities of contemporary explainability techniques—they can produce broad descriptions of how the AI system works in a general sense but, for individual decisions, the explanations are unreliable or, in some instances, only offer superficial levels of explanation.”

Profs. Ruonan Han and Qing Hu speak with Popular Science reporter Rahul Rao about their work with terahertz waves. “There’s a laundry list of potential applications,” says Hu of the promise of terahertz waves.

MIT engineers have developed a new contactless method to clean solar panels that could save billions of gallons of water, reports Anuradha Varanasi for Popular Science. “I was amazed at the sheer amount of pure water that is required for cleaning solar panels,” says Prof. Kripa Varanasi. “The water footprint of the solar industry is only going to grow in the future. We need to figure out how to make solar farms more sustainable.”

Prof. Sara Seager has been awarded one of NASA’s Innovative Advanced Concepts (NIAC) awards, which will help fund her project aimed at sending an orbiter that deploys an inflatable probe to Venus, as part of an effort to search for habitability or signs of life, reports Ramin Skibba for Wired. “This search for signs of life on Venus has been around for a long time, and now the stars are aligned to start taking it seriously,” says Seager.

Daily Beast reporter Miriam Fauzia writes that MIT researchers have developed a new way to create carbon fibers that are stronger and lighter than steel, using leftover waste from crude oil processing. “The new findings could usher in an age of heavy-duty cars that consume less fuel thanks to their decreased weight,” writes Fauzia.

Hill reporters Saul Elbein and Sharon Udasin spotlight how MIT researchers have developed a way to make lightweight fibers for possible use in the bodies of cars out of the waste material from the refining of petroleum. “The ‘heavy, gloppy’ leftovers from the petroleum refining process could become a key ingredient in making electric vehicles lighter, less expensive and more efficient,” they write.

Researchers from MIT and MIT spinoff Quaise Energy speak with Boston Globe reporter David Abel about their work developing a new way to drill as deep as 12 miles into the Earth’s crust, using a special laser, which could provide a way to tap the geothermal energy in the rocks. “This is game-changing,” Woskov said. “We now have the potential to exploit an energy source that . . . could unleash the virtually limitless supply of energy beneath our feet.”

MIT researchers have created a new computer algorithm that has allowed the mini cheetah to maximize its speed across varying types of terrain, reports Shi En Kim for Popular Science. “What we are interested in is, given the robotic hardware, how fast can [a robot] go?” says Prof. Pulkit Agrawal. “We didn’t want to constrain the robot in arbitrary ways.”

Prof. Kripa Varanasi, graduate student Sreedath Panath, and a team of researchers are developing a water-free way to clear dust off of solar panels, reports Billy Hurley and Ed Brown for Tech Briefs. “Water is such a precious commodity, and people need to be careful about how to make use of this resource that we have,” says Varanasi. “The solar industry really needs to keep this in mind; we don’t want to be solving one problem and creating another.”

MIT researchers have used a new reinforcement learning system to teach robots how to acclimate to complex landscapes at high speeds, reports Emmett Smith for Mashable. “After hours of simulation training, MIT’s mini-cheetah robot broke a record with its fastest run yet,” writes Smith.

Professor Linda Griffith speaks with Radio Boston host Tiziana Dearing about her research on endometriosis. The dream is “that we get diagnosis at the start, and you get your therapy at the start, and you don’t even develop the disease,” says Griffith.

Prof. Yoel Fink speaks with WHDH about his team’s work developing an acoustic fabric that can listen to and record sound, a development inspired by the human ear. "The fabric can be inserted into clothes to monitor heart rate and respiration. It can even help with monitoring unborn babies during pregnancy."

CSAIL researchers developed a new machine learning system to teach the MIT mini cheetah to run, reports James Vincent for The Verge. “Using reinforcement learning, they were able to achieve a new top-speed for the robot of 3.9m/s, or roughly 8.7mph,” writes Vincent.

Gizmodo reporter Andrew Liszewski writes that CSAIL researchers developed a new AI system to teach the MIT mini cheetah how to adapt its gait, allowing it to learn to run. Using AI and simulations, “in just three hours’ time, the robot experienced 100 days worth of virtual adventures over a diverse variety of terrains,” writes Liszewski, “and learned countless new techniques for modifying its gait so that it can still effectively loco-mote from point A to point B no matter what might be underfoot.”

MIT has announced the creation of a new multidisciplinary center, called Morningside Academy for Design, which is intended to serve as a “focal point for design research, education, and entrepreneurship,” reports Michael T. Nietzel for Forbes.
